[Dovecot] fts_squat + virtual => crash

[intrigeri]

Hi,

dovecot's imap process segfaults when I search a virtual mailbox using
the fts_squat plugin. Is this supposed to work, or a known bug?
I've seen some changes commited to fts_solr a couple of months ago
that where supposed to fix search issues on virtual mailboxes, maybe
fts_squat needs to be fixed to?

backtrace
=========

As I'm using Debian's 1.2.1 package, the debugging symbols
are stripped. Tell me if a backtrace with debugging symbols enabled
would help debugging this problem.

Here's the backtrace anyway:
